1 Corinthians 14:18
14:18 I thank God that I speak in tongues more than all of you,
1 Corinthians 14:21-23
14:21 It is written in the law: “By people with strange tongues and by the lips of strangers I will speak to this people, yet not even in this way will they listen to me,” 1 says the Lord.
14:22 So then, tongues are a sign not for believers but for unbelievers. Prophecy, however, is not for unbelievers but for believers.
14:23 So if the whole church comes together and all speak in tongues, and unbelievers or uninformed people enter, will they not say that you have lost your minds?
1 Corinthians 14:29
14:29 Two or three prophets should speak and the others should evaluate what is said.
